Abstract

PCT No. PCT/FR92/00408 Sec. 371 Date Oct. 26, 1993 Sec. 102(e) Date Oct. 26, 1993 PCT Filed May 6, 1992 PCT Pub. No. WO92/19364 PCT Pub. Date Nov. 12, 1992A method of cleaning gases includes introducing a gas containing organic pollutants into a scrubber and providing a scrubbing liquid. Finely divided solids capable of remaining substantially in suspension in the scrubbing liquid are introduced into the scrubbing liquid and the gas is wet scrubbed to remove the organic pollutants as dissolved gases and as particulate. A reagent capable of reacting, in combination with the finely divided solids, with the organic pollutants removed from the gas, is introduced into the scrubbing liquid to convert the removed pollutants into different compounds. A major portion of the scrubbing liquid is reused in the wet scrubbing.
